Chapter 3: Totally Excellent Adventure!
"Waitaminute!", Candace said, "You're telling us that you two are really Bill and Ted?". Bill and Ted nodded. "BWAHAHAHA, That's funny. HAHAHAHA!". Phineas and Ferb thought that they would be hurt by this comment. They weren"t
Bill and Ted had a quizzled face, and Jimmy just had a smile on his face. "Non-believers don't get a ride.", he said. Candace stopped laughing for a moment, then looked at the booth. "Did you guys say that soon will invent it?", she said. Jimmy nodded, and added, "In the future.". "Ooh! You guys are so busted.", she said. Then she ran into the house to get her mom.
"Dude, let's get outta here!" "I agree Ted.", Jimmy said, closing the console. He then started dialing a number. The booth hummed to life, ready to lift off. "You guys coming?", Jimmy said. Phineas and Ferb shrugged, then got in. Phineas closed the booth door, and thus it began.
The antennas popped up, activating the booth, preparing for its destination. "Gentlemen...", he said, putting on his goggles, "We're past tense.". Soon, they launch off.
Candace opened the sliding glass door, hoping that the booth was still there. "And what am I looking at?", Linda said. Candace looked to see that the booth had left. What she didn't notice was that the boys was gone, or the electric smoking square.

The booth flew through the Circuits of Time and Space, (properly named) while keeping the five boys safe. "These must be the Circuits of Time.", Phineas exclaimed. "...and Space.", Jimmy added. Phineas looked at Jimmy, curious on the new name. "Since the booth can now travel to other dimensions, we renamed the circuits to The Circuits of Time and Space. They allow access to places and times." "Cool!", Phineas and Ferb said.
Soon, a booth flew out of a hole, falling to the earth below, past the clouds. Meanwhile, as Marty started heading into the garage, he saw a storm coming. "I better get inside.", Marty said. As soon as he did, a phone booth landed safely onto the ground, on a sidewalk. Everyone got out, looking around their new environment. Phineas and Ferb were partially surprised that they were still alive after that fall that happened. "Where and when are we?", Phineas said.
All of a sudden, they hear a powerful guitar riff rattle the windows of the garage across from them. "Hill Valley, California. 1986. Six months after Back to the Future Part III. Marty's adventure is about to begin...", He paused, checking his watch, "... Riiigghtt- NOW" *BANG! BANG! BAH-WOOSH!* Soon a DeLorean appeared, frozen cold after time traveling. Jimmy motioned for them to hide in the booth. As soon as they partially closed the booth door, Marty came out to see the DeLorean, surprised to see it there. The last time he'd seen it was when the train destroyed it and Doc invented the Time Train in 1886. He went to touch it only for his hand to recoil from the coldness.
"Most Excellent!" *air guitar*, Bill and Ted exclaimed. Jimmy nodded as he dialed in the number. "See, I told you there was a part 4", Phineas said. Jimmy waved his hand in a 'kinda' action, and hummed in a 'Well...' tune. "Well, what?" "Actually, you could count it as part IV, but it isn't.", Jimmy said. "How?", Ferb said. Jimmy explained it in three words. "Episodic Video Game.", he said, then hung up the phone. The booth fully closed as both antennas popped up. Marty looked up from the time circuits to see a somewhat familiar phone booth, launching off. He then shook his head, curious if he would see any phone booth like that again.

Phineas and Ferb couldn't believe it. They were in the world of Back to the Future. "Dude should we them?", Ted said. "Yea dude!", Bill said. Jimmy nodded in agreement, then handed them the "Squint Directory". He held it open to a page showing a kid with a triangle head, wearing a striped shirt, and a long faced kid with odd clothing. "That's us.", Phineas said. "You mean, we're fictional?", Ferb said. Jimmy shook his head, then leaned in. "Let me tell you a theory that a guy explained to me.", Jimmy said. Both nodded, wanting answers. So as the booth flew through the circuits, Jimmy explained his theory that he heard from a fellow inter-dimensional traveler that was human.
As soon as he was done, that's when the booth shook a little for a brief second, before heading out one hole and landing in a forest. "Look, that must be Robin Hood.", Phineas said, pointing out the hooded figure. "Where are we?", Bill said. All of a sudden, they heard a whistling sound. Soon, two people landed on the ground. One had shaggy hair, and a red and white T-shirt. He even had Nikes on his feet. The other one looked like he had a leather vest, a white shirt, and leather boots.
"Whoops. Wrong place and time.", Jimmy said, picking up the phone and dialing the number in. "We've landed in the Voyagers TV Series.", Jimmy said. Bogg and Jeffrey looked around the place they've landed in this time. Jeffrey soon spotted something out of time in this time period. He remembered that phone booths weren't around in the 17th century. They existed in his time. "Bogg, look.", Jeffrey said. Bogg looked in Jeffery's general direction that was pointed at to see a phone booth. Two heads popped out, waving. "How's it going, dude?", the Wyld Stallyns said. Several hands grabbed the duo and pulled them in, closing the booth doors behind them. "Let's go have a look.", Bogg said. Jeffrey nodded in agreement, then followed the Voyager to the booth.
Soon, two antennas popped up, sending streaks of electricity though the booth. Soon, it launched by opening the circuit, grabbing the booth with electrical tentacles, then dragging it into time itself. Both Phineas Bogg and Jeffrey Jones were surprised by the sudden disappearance of the booth itself. Only one word left Jeffrey's mouth. "How?", Jeffrey said. Phineas just shrugged, grabbing his Omni and opening it.

The booth continued to fly though the circuits, as the boys hoped to land somewhen and where safe.

Bill and Ted Universe
1989
San Dimas, CA
The mall seemed quiet in a way. The only people there was Bill and Ted's girlfriends. All of a sudden, there were flashes of light. Looking up, they saw that the lightning was unusual, unless there was a phone booth involved. Soon, the phone booth landed at the mall, surprising them.
The phone booth opened, and Bill and Ted stepped out. They soon saw Joanna and Elizabeth. "Hey, what's up?", They both said. Their finances ran up to them, and hugged them. Phineas and Ferb climbed out of the booth, surprised that they had landed in the 1980's.
"Where and when are we at?", Phineas said. Jimmy stepped out of the phone booth, looking around. He lifted his goggles, then said, "San Dimas, California. 1989, in Bill and Ted's Universe. A year after their Excellent Adventure.". Phineas and Ferb nodded, then Ferb said, "Well, that explains it.". Soon Bill and Ted brought their fiancees over to meet the two inventors. "Phineas, Ferb, this is our finances, Joanna and Elizabeth." "Hello.", Joanna said. "Hi.", Elizabeth said. They shook hands, smiling. Then, the two girls noticed the new operator and the phone booth as well.
"Is that Rufus?", Elizabeth said. Jimmy turned toward them, smiling. "No, Rufus is sick. I'm Jimmy.", he said. Ferb looked at them, and said, "So, where are you ladies from?". "We came from England in the 17th Century.", Elizabeth said. Ferb was impressed on the on when they came from. As he heard the story of how Bill and Ted met them, and of Rufus' rescue, Jimmy heard the phone rang. Jimmy walked to the booth, and picked up the phone. "Hello?"

Meanwhile, Back at the Phineas and Ferb Universe...
Isabella stepped into the backyard to see Candace sitting and waiting. "Hey Candace. Watcha' doin?", she said. Candace looked at Isabella, then looked back at the backyard. "Waiting for my brothers.", Candace said. Isabella was curious on the whereabouts of Phineas, so she asked, "Well, where are they?". Candace sighed in exhaustion, then said, "I have no idea."

Back at the Bill and Ted Universe...
"Cool, see you soon.", Jimmy said. He then hung up and climbed out of the booth. "Guys, I just got a call. We're invited to a wild party happening soon.", he said. "Excellent!", Both Bill and Ted said. "Yes, well. I'll have to drop off Joanna and Elizabeth first. Then, I need your help in getting the party guest. Joanna and Elizabeth entered the booth as Jimmy dialed in the number. Phineas was curious about this party. "Who's hosting it?", He said. Then Ferb added, "Where and when is it?". Jimmy hung up the phone, then said, "Uh, our host wanted it to be a surprise. The only thing I could tell you was that it was a party.". Bill and Ted nodded, then said, "That makes sense.". Both Joanna and Elizabeth waved goodbye as the booth doors closed.
Soon, the booth launched off. Five seconds later, the booth returned with Jimmy in it. "Alright let's go.", he said. Phineas, Ferb, Bill, and Ted all got into the booth. Jimmy dialed in the number, indicating that things were going to get 'Most Triumphant!' for the five of them.
